- the steering control unit 124 determines whether the amount of lateral change of the preceding vehicle LV detected by the preceding vehicle detecting unit 123 is less than a predetermined amount. When it is determined that the amount of lateral change is less than the predetermined amount, the steering control unit 124 proceeds to S 50 . In S 50 , the steering control unit 124 performs the steering control so as to follow up the lateral position of the preceding vehicle LV.
- the steering control unit 124 proceeds to S 60 .

For this reason, in S 60 , the steering control unit 124 causes the motor 5 to stop the auxiliary assistance, thereby stopping the steering control.

- the vehicle control device 10 stops the follow-up control to suppress the straight advancing from being deteriorated. Thereby, the vehicle control device 10 can cause the vehicle V to stably travel.
- the present disclosure achieves the effect of causing the vehicle to stably travel, and is useful for the steering control device, the steering control method and the like.
